Amazon Echo Dot (2nd Generation), Black: Amazon.co.uk: Kindle Store

I have the original Amazon Echo (the tall one), a 2nd generation (the squat one) and recently purchased an Echo Dot (2nd generation) along with a Bluetooth speaker that I bought specifically to use with it, so I thought it time to post a review comparing the two full size versions against the experience of the Dot. First, as we all know, the Dot has small, tinny speakers which are the equivalent of what you would get from playing on a mobile phone... all fine and as advertised as you can either connect external speakers via Bluetooth or wired. Dependant on what you attach to it you can get audio which could potentially be better than the built-in speakers of the full size devices. What I didn't appreciate was that if you have multiple Echos and are hoping to use the Multi-room audio functionality, if any of your Echos are connected via Bluetooth to an external speaker then the music will not play on that speaker but will revert to the speaker on the Echo itself. I spent an hour thinking I'd set things up incorrectly or the Bluetooth speaker was at fault before I realised.
